I have a banty hen that has been setting on 15 eggs (5 banty eggs and 10 stolen standard size egss that she stole from another standard size Black Australop that would visit her nesting box and lay). Well she has hatched 4 of her banty eggs and 3 of the standard eggs. She is an excellent mother !!! 2 of the eggs are pipping and have been pipping for 37 hours now. I do not want to intervene but I'm getting worried. Do I let nature take it's course and let the chick hatch by themselves or do I intevene and help? I do not want to hurt the chicks but I'm scared that 37 hours has been too long. Because she would steal the eggs daily, the hatching is staggered. Every day an egg is hatched. What should I do? Please help !
